A vulva sniffer is somebody who has an obsessive behavior to sniff the vulva before sex or any act of sexual fun. They will place their nose right on the vagina lips and take 5 big fat sniffs. If they don't mind the smell, they will carry on with the sexual pleasures they were giving. If the smell isn't to their personal taste. They usually flick the woman's bean and then leaves them to finish themselves.
Vulva sniffers are very judgmental and can make people feel very uncomfortable
